An explorer from Herefordshire, Henry Worsley, 55, has died following an attempt to cross Antarctica, completely unaided. He suffered exhaustion and dehydration, and was airlifted off the ice on Friday.

He had spent 71 days alone in Antarctica, and was on the brink of making history with a solo crossing across the ice. His goal was to become the first adventurer to cross the continent completely unsupported and unassisted. He had covered more than 900 miles, and he was just 30 miles shy of completing his goal.

Mr Worsley, who had previously worked as an Army officer, had shared his journey on Twitter, via @shackletonsolo. The final post, on Saturday, January 23rd outlined: "Henry Worsley is now in hospital in Punta Arenas with peritonitis. His wife Joanna has flown to join him. No further news until Tues 26-1-16."

The attempt had been win aid of the Endeavour Fund, a charity which supports the recovery of wounded, injured and sick Servicemen and women.

Harry Holt, Chairman of the Endeavour fund said: “We are devastated by the loss of Henry Worsley. The Endeavour Fund is very proud to have been associated with Henry’s tremendous achievements but we mourn his sacrifice. Our thoughts and prayers are with his family and friends in this dark hour.”
